Probably not the best coding, but get over it.

How to use it?
Link the image, (eg call that php file index.php)
so in HTML it be like

<img src="index.php">

and to make it link to the website you requested like this

<a href="index.php?cmd=link">
 <img src="index.php">
</a>

or in BB CODE

[url="http://kg-hosting.co.uk/sig/index.php?cmd=link"]
[IMG]http://kg-hosting.co.uk/sig/index.php[/IMG]
[/url]

array ( 'img.jpg', 'url2site.com' ),
                                 array ( 'img2.jpg', 'url2site2.com' ),
                                 array ( 'img3.jpg', 'url2sitex.com' ) 

So i need to change that bit for the image and link yeh?

[Protege]

Correct, add as many as you like. jpeg,gif,png

[RyanDOT]

Fantastic +Rep.

And i put you to my owed rep list so i can rep you again when i can.

[Dentafrice]

Just an idea, to save a lot of coding, as you have matched each file type and used an imagecreatefrom[format] approach.

An easier way would be getting the contents of a file, either using file_get_contents or fopen() to read it.

Then using imagecreatefromstring() which doesn't require you have all that code, then you can output it

[Protege]

I don't amend the code I publish, that's for the other people to do. ]

I'm probs gunna get knifed by ifuse for hosting an image exchange, if this counts as one

[Dentafrice]

Well as long as you have the bandwith, I don't think they will say anything.

[Protege]

In their TOS, it says they don't allow a banner exchange (I basically revised it after some-what-****-of-a-josh put **** on his acc) I also think the "random" is not that random, seems always to hit number #1

[Dentafrice]

Hmm, well.. maybe they won't notice

[Protege]

maybe not, ontopic posts only now, I think i'll edit mine to check if its last one was the one its just randomized, then choose another.
